Construction Management Awards

West Yost provided design and construction management services to expand the existing 14-Mile Slough Pump Station (14-MSPS) by nearly 700%. This project represents one of the largest trench-style wetwell pump stations in California. The award-winning pump station upgrade increased reliable pumping capacity from 3.75 mgd to 14 mgd, with a buildout capacity of 22.5 mgd.

West Yost provided planning, design, and construction management for the Ophir Road Pump Station. This pump station constructed about a mile upstream and 210 feet above the Auburn Tunnel outlet, allows Placer County Water Agency (PCWA) to pump water from the tunnel for municipal and agricultural use. It is designed to pump 332 cfs of water through three distinct pump stations, housing 11 vertical turbine pumps ranging in size from 200- to 600-hp.

West Yost provided planning, analysis, environmental review, permitting, design, and construction management services for the Dry Creek WWTP Levee Relocation. This project included the hydrologic and hydraulic analyses of Dry Creek in the vicinity of the WWTP. The project provides 100 year protection of the wastewater storage ponds while enhancing the flow carrying capacity of Dry Creek in an environmentally sensitive manner.

West Yost provided the predesign, design, and construction management and inspection for a partially buried, 3 MG potable water concrete storage tank and a 6,000 gpm booster pump station located in the City’s David Douglass Park.

The objective of Roseville’s Aquifer Storage and Recovery (ASR) Program is to store surplus drinking water (10,000 acre-feet per year) in the underlying aquifer during periods of normal and above normal precipitation. This stored drinking water is then extracted and served to meet peak demands. West Yost provided design and construction management services for two ASR wells for the City.
